How does double glazing work?

by | Aug 9, 2016 | Glazing

Ask any homeowner what they most desire and it will probably be a climate-controlled home. When you are able to keep your home warm in winter and cool in summer, you have comfortable living conditions year-round. The problem is that old-fashioned single-paned windows or doors are particularly bad in this regard. Glass is an excellent conductor of heat, allowing warm air to move readily through it. As a result that warm air that makes your home cosy and which costs energy to produce, slips out through these windows and warms up the environs around your house!

Likewise, in summer, a glass room, such as a conservatory, becomes the proverbial hotbox in summer and can be entirely unpleasant to spend time in. However, people love having glass in their homes. It’s the only way to get in natural light and to enjoy views of the garden or the scenery around the house. The answer is very simple, and that is to invest in double glazing in Farnham home.

The secret to double glazing

If double glazed doors or windows were simply an extra sheet of added glass, it would make a difference, but only a slight one. The secret with double glazed windows is that there is a gap between the two sheets of glass, which is usually not more than about half an inch. This gap is usually filled with an inert gas, and this is the secret to the design. The gas used isn’t a good conductor of heat, and thus it prevents the easy heat exchange through the two panes of glass. Having this insulation has a dramatic effect, and can reduce energy bills by up to 50%. Triple-glazed windows are also available, but research has shown that these are not necessarily better than having double-glazing.

Choosing double glazed windows

You can choose from a wide variety of windows styles and different frames. You need to check on the efficiency of the windows, as some are more energy-efficient than others. This is normally rated on the amount of air that is able to escape between the window frames and the walls, and the actual heat that still passes through the glass. You need a very well-sealed window with double glazing that has low emissivity glass for the best result.
